The UDK Object Generator allows to generate objects from a map file in a text format. This text can be pasted directly into UDK as long as you have the dummy assets.
Start by selecting an upk file from the game CookedPCConsole folder.
Generate with the invisitek materials instead of normal ones when applicable
Will generate every object with a layer (for UDK) named as the object type
Select which object types to include in the generation
